Knock boxes

The knockbox has become an essential accessory for any place that values efficiency and cleanliness in coffee making.

Disposing of coffee grounds from the portafilter the right way also protects the portafilter from damage in the long run. 

You would be able to find knockboxes of all shapes and sizes to fit your needs, whether it is a small counter top knockbox for your kitchen, or a built-in knockbox for the cafe bar.
Drawer style knockboxes saves space and keeps the grounds cleanly tucked away.
